Both Paley and Malthus afforded Darwin much food for thought; ‘nature
has scattered the seeds of life abroad with the most profuse and liberal hand’,
Malthus had declared. Slaughter, it could be argued, was utterly necessary.
For otherwise each tiny square of Earth would be overrun by millions of
clamouring creatures. Malthus’ lesson: infinite multiplication and crowding
are necessarily held in check by waste, sickness, destruction, misery and vice:
population, unchecked, necessarily outstripped resources: ‘I see no way by
which man can escape from the weight of this law which pervades all
animal nature’ (Malthus 1988,p.72). For Darwin, the imbalance between
population and resources is not to be understood as a flaw in the system
of nature; on the contrary, it constitutes the necessary mechanism, the very
precondition of natural selection.
2 Science and authority
In the age of Darwin, words such as ‘science’ and ‘scientist’ were often
invoked to convey a sense of moral and political impartiality. ‘Scientist’ was
eventually to suggest a member of a trained, professional (salaried) caste,
but it was also to be adopted to connote a particular kind of neutral stance.
Such credentials were strongly claimed, for instance, by Darwin’s polymath
cousin, Francis Galton (1822–1911), even as he advocated policies that were
anything but value-free. Darwin, who had thought very highly of some of
Galton’s earlier work,
18
died before the latter’s full eugenic ambitions had
become apparent, and we can only speculate on whether he would have
considered these equally admirable.
19
Galton coined the word ‘eugenics’ in
1883. It set the seal on his already prolific enquiries into heredity, genius,
natural design which led to the (not precisely equal) ratio of the sexes. Many commentators
insisted on the indissoluble link between fecundity and the best possible economy of nature (La
Vergata 1990). Thus social and physical ills that stymied reproduction were really a blessing in
disguise. Prostitution was deemed by some writers to be a necessary antidote to excessive fecundity
whilst even venereal disease was occasionally mooted as helpful, since indirectly it might curb the
population.
18 Darwin offered some encouragement but did not directly endorse his relative’s more specific ideas
and proposals. Galton could not accept the implied equation of fitness with fertility, given that the
poor were the most fecund. The struggle for existence, he suggested, as he looked darkly at the
Victorian city, ‘seems to me to spoil and not improve our breed’. On this correspondence, see
Himmelfarb 1952,pp.326–7; Jones 1980,p.100;cf.Forrest1974. For reflections on these issues in
The Descent, see Darwin 1871, i,pp.177–8.
19 Darwin occasionally urged his family as well as colleagues to think twice before drawing sharp
political or atheistical conclusions from science. ‘I venture to advise you not to carry the deg radation
principle too far’, he wrote, characteristically, for example, to the zoologist Anton Dohrn (letter, 24
May 1875, in Dohrn 1982,p.63).
